Zunjue, 3M, Ray-Ban and Dragon Film, but there are many fake brands of 3M and Ray-Ban, and Zunjue is a product launched by Joinns. Because it has just entered the market, there are no fakes on the market at present, but the quality is excellent. The specific landlord can search "Joinns Owner Service Network" for more information. The film is not only beautiful, but also closely related to the owner's safety. Please be sure to read it before posting it. First of all, the storefront is not formal enough and the operation workshop is standardized. The most important thing is the quality of the film. The following is the way to tell the landlord how to distinguish the quality of the film:

First, the special dust-free film pasting room-after the film pasting on the car window, there can be no defects and debris particles, so the professional installation must be carried out in the dust-free film pasting room! The clean room not only has a closed glass door isolated from the outside, but also has a water mist nozzle and air conditioner to realize air dust removal, and the ground has a drainage ditch and special paint to further realize dust removal.

There is a dedicated workbench and articles in the room, which are neatly arranged. The installation effect under such a construction environment is by no means achievable by street open-air operation.

Second, professional tools-unprofessional tools such as shovels can't squeeze the water clean, leaving blisters and bubbles, which are more likely to scratch the film; Carbon steel blades may scratch high-grade automobile glass ... unprofessional shops usually use domestic or homemade unprofessional tools, which are rough in material and fuzzy in function, and often serve multiple purposes. Most of the professional laminating tools are imported from the United States, with clear classification, beautiful appearance and easy identification.

Third, special chemical liquid-professional automobile film should use special film cleaning liquid and installation liquid, and dilute with pure water, so that the film and glass can achieve the maximum bonding strength, and will not cause defects such as edge warping and delamination, and achieve long-term quality assurance effect. Non-specialty stores are using household cleaning agents, ordinary soap and tap water, which cannot provide professional installation and warranty period.

Four. Installation technology-professional film pasting technicians should receive technical training from manufacturers (the training certificate should be hung in the store), and the whole paving and dry heat setting process should be adopted when pasting the front and rear windshields, and the film should be pasted on the edge of the glass window as far as possible ... When pasting the front and rear windshields, non-professional installers should spray the car glass wet first, then spread the film on it, and then set it with a hot gun, which may cause excessive thermal stress and uneven heating to the glass, resulting in the glass breaking on the spot or within a few days after pasting.

Verb (verb's abbreviation) protection measures during installation-professional installation should take good protection measures: prevent the paint surface from being scratched by moisture during installation, damage the interior decoration, and cause short circuit failure of the electrical appliances and audio in the car; Avoid seat damage caused by window film installation and failure caused by accidental scratch or damage on the instrument panel surface.

Six, the appearance quality evaluation standard-car film professional installation:

(1) There should be no defects and sundries in the film, and there should be no creases and bubbles on the film surface; Stains, defects and sundries accumulated in the film are signs of low-quality installation.

(2) There should be only 1-2mm micro-gap at the top of the hem window, which is not easy to find by rough observation.

(3) The black glaze point area of the glass frame should be covered, without light leakage or edge warping, which is beautiful and harmonious.

(4) There should be no visual ghosts and watermarks caused by uneven extrusion force and irregular extrusion path.
